Title: Magnesia-base slag formation promoter for refining limy flux and its production
Inventor: TAJIMA RITSUO
IPC: C21C7/076
Filed: 1994-03-04
Abstract: PURPOSE: To improve the action of a magnesia-base additive to promote the slag formation of a limy flux having a high m.p. CONSTITUTION: A magnesia-base slag formation promoter to be introduced into the molten metal to promote the slag forming action of a refining limy flux consists essentially of light-burned magnesia (MgO), and 10-30wt.% magnesium hydroxide Mg(OH)2 is incorporated into the magnesia. The magnesium hydroxide is naturally mixed in the light-burned magnesia when the magnesia as the main component is added with water, granulated to an appropriate size and dried. The magnesium hydroxide having a low m.p. of 350 deg.C easily forms a low-m.p. compd. with high-m.p. MgO and the CaO as the main component of the limy flux, hence the slag forming action of CaO is promoted, and desulfurization and dephosphorization are conducted in an early stage.

Title: Information recording/reproducing device
Inventor: YOSHIO JUNICHI
IPC: G11B20/10
Filed: 1988-03-16
Abstract: PURPOSE:To decrease quantizing noises by deciding the level of an input signal for each prescribed period and controlling said level for each prescribed period based on the result of said level decision to record this signal level. CONSTITUTION:The level of an input signal S1 is detected for each prescribed period T for decision whether this level is lower than a fixed level or not. If so, a level switch signal S5 is transmitted for control of an input switch circuit 12 and selection of an output signal S2 of an amplifier 11 which are performed by a level deciding circuit 15. The selection of the signal S1 or S2 is recorded on a subcode included in the recording data S4 produced by a writing circuit 14 as level switch data based on the result of decision of the circuit 15. Furthermore, the digital data read out of a recording carrier is converted into an analog signal and the level of this analog signal is controlled by the data showing the result of decision. In such a way, a low-level signal which is easily affected by the equalizing noises is amplified and recorded after D/A conversion. This signal level is reset to its original level at the time of reproduction. Thus the equalizing noises can be decreased for the low-level signals.

Title: Time base corrector device
Inventor: KIHARA KENICHI
IPC: H04N5/956
Filed: 1993-02-24
Abstract: PURPOSE:To provide a time base corrector device which can generate plural frequency clocks without becoming complex in constitution by providing a reference frequency signal generating means, a switching means, and a phase modulating means. CONSTITUTION:A synchronous separation part 1 separates a horizontal synchronizing signal from an input video signal and supplies it to a phase modulation part 4. Clock sources 5 and 6 which generate reference clocks differing in frequency are connected to the phase modulation part 4 through a switch 7. The phase modulation part 4 matches the phase (rise timing) of a clock supplied through the switch 7 with the phase (fall timing) of a horizontal synchronizing signal outputted from the separation part 1 and outputs it as a sampling and write clock. Consequently, even when plural clock frequencies (sampling clock frequency) are required, the hardware constitution does not become complex correspondingly and the cost is reduced.
